I find this notion worthless and misguided. Being a fascist is a product of deliberate ignorance, not a failure to understand. Her mind wasn't shockingly expanded when her father died. She just got angry enough about the injustice of her situation to slightly abandon her spiteful disdain for all things progressive and good for the people and the world.
Note her repeated insistence that the right and the left both want safer roads. It is not and never has been the left pushing for roads to be less safe. The fascists adopted road safety as another cause they could ideologically appropriate for the cause of disdain. The fascist ideology requires a constant never ending source of outrage, even after they have taken power. The enemy must always be present and scheming with trivial political matters. Everyone is aware that roads being less safe will result in more people dying. They just do not care. They disdain the idea of caring. They disdain the idea of doing something to make roads safer.
